4 Claims.

My invention relates to improvements in needle threading devices. The particular object of the invention is to provide means capable of attachment to the end of a spool of thread or the like which will be cheap to manufacture and serve to hold the free end of the thread against unwinding, to sever the thread and to provide means whereby a needle may be conveniently held, and means by which a needle may be quickly and conveniently threaded. A further and important object of the invention is to'provide means whereby the eye of the needle to be threaded is aligned with the threading tongue, so that the needle may be accurately moved onto the threading tongue. I

The invention consists essentially of a plate adapted for attachment to a spool, said plate being fitted with a needle threading tongue and having an indent in which the eye end of a needle is placed and subsequently moved towards the needle threading tongue, as will be more fully described in the following specification and shown in the accompanying drawing, in which Fig. 1 is a perspective view of the invention.

Fig. 2 is a plan view showing a modification of the needle end aligning and guiding means.

Fig. 3 is a sectional view taken onthe line 3-3 of Figure 2.

Fig. 4 is a perspective view of the threading tongue support slidably mounted and the needle aligning means shown in Figures 2 and 3.

In the drawing like characters of reference indicate corresponding parts in each figure.

The numeral l indicatesa spool wrapped with thread 2 having a free end 3. The numeral 4 indicates a disc or plate preferably circular in form and having a plurality of downwardly turned points 5, shown in dottedv line, struck out from its surface which are driven into the end grain of the spool I to secure the disc thereto.

An indent 6 is formed in the disc 4 which is in the nature of a groove 1 of V-shaped cross section and a channel 8 consisting of a parallel sided throat 9 intersecting the groove 1 and a substantially triangular portion Ill having its apex terminating in the throat 9. At one end I of the groove 1 a threading tongue II is supported, which consists of a thin blade capable of projecting through the eye of a needle and having on one edge a notch l2 in which the thread is adapted to be laid. The tongue is spaced from the bottom of the groove 1 to ensure the eye of the needle passing onto it, when said needle is drawn in upright position with its eyed end in contact with the base of the groove.

The centre of the disc 4 is apertured as at l3 to coincide with the core 84 of the spool i and in the aperture a tab 15 is formed which is downwardly curved until its free end closely approaches the side wall of the core M. The tab i5 is provided with two orifices it through which a needle is adapted to be inserted and are so aligned that the needle when so inserted will tend to bear against the side wall of the core M to prevent free endwise movement of the needle.

Formed upon the periphery of the disc 4 by a cut I1 is a lip l8, which lip is slightly raised at its free end to allow the thread to pass underneath it and be severed at the inner end of the cut. The lip 18 is indented longitudinally to form a rib I9 on its underside, which coacts with the head of the spool to grip the free end of the thread and hold it against unwrapping from the spool.

In .the modification shown in Figures 2, 3, and 4, the disc is provided with a cup 26 having sloping side walls 2| and a recess 22 at its base conforming to the section of the eyed end of a needle and being so disposed that when a needle is placed therein its eye would be at a right angle to the threading tongue ii. The side walls of the cup are cut through as at 23 to form a passage of requisite width to allow the eyed end of a needle to slide transversely into the groove 1.

The modification shown in Figure 4 shows the threading tongue ll mounted upon a removable slide 24 which is slidably mounted in guides 25 formed in the disc 4-. A suitable stop 26 is also formed in the disc so that when the slide is pushed into contact therewith the threading tongue will be aligned with the groove "i.

In threading a needle, the eyed end thereof is inserted into the triangular portion ll] of the indent 6, see Figure 1, and is moved sidewise, which tends as the needle engages the sides of the triangle and approaches its apex to align the eye so that it is transverse to the throat 9 and parallel to the threading tongue H. The needle is then passed through the throat 9 into the groove 1 along which it is moved towards and onto the threading tongue H where it assumes the position shown. A length of thread having been withdrawn from the spool is passed under the holding lip l8 and out off thereby. One end thereof is laid over the notch l2 and the needle is withdrawn over the bight of the thread held by said notch, thus leaving a loop through the eye of the needle. The short side of the loop is then drawn through the eye and the threaded needle is ready for use.

After use the needle is inserted through the two orifices [6 in the tab l5, which are so disposed in the curved tab as to cause the needle to be frictionally held therein, alternately the tab may be so bent that the needle point leads towards and engages the side Wall of the core, thus providing frictional engagement with the wood.

What I claim as my invention is:

1. A needle threading device comprising a plate having a groove adapted to receive the eyed end of a needle, a threading tongue supported above one end of the groove and eye aligning means adjacent the other end of said groove.

2. A needle threading device comprising a plate having a groove adapted to receive the eyed end of a needle, a threading tongue supported above the groove and means intersecting the groove remote from the threading tongue for urging the eye of the needle to'turn into alignment with the threading tongue.

3. A needle threading device comprising a plate having a groove adapted to receive the eyed end of a needle, a threading tongue supported above the groove and means intersecting the groove remote from the threading tongue for urging the eye-of the needle to turn into alignment with the threading tongue, said eye aligning means consisting of a needle end receiving recess, a passage communicating between the recess and the groove, said passage being of a width conforming substantially to the minor transverse dimension of the eyed end of the needle and less than the major transverse dimension of said eyed end.

4. A needle threading device comprising a plate having a groove adapted to receive the eyed end of a needle, a needle threading tongue supported above and parallel to. the groove, an indent adjacent the groove consisting of a triangular portion and a throat, said throat communicating between the triangular portion and the groove.
